Your article says: "In most places El Pretérito Indefinido will be used with "nunca" and "siempre" and even with time expressions which have a connection to the present, such as: hoy, este mes, este año, esta noche, esta mañana, esta semana..."
On a quiz, I used the indefinido in a question with a "time expression which has a connection to the present" (i.e. "hoy") and got the question wrong-- it was corrected to the perfecto.
Is there something wrong with what I did? Are the quizes looking for peninsular or latin american answers?
